Furthermore, the outer side of the limiting block 214 is movably sleeved with a positioning ring 221, the outer side of the positioning ring 221 is connected to the inner surface of the limiting seat 212, one surface of the two half-curved bars 216 is connected with a positioning sleeve 222, a positioning rod 223 is inserted into the positioning sleeve 222, one side of the positioning rod 223 is connected with the finger ring 217, and the positioning rod 223 outside the positioning sleeve 222 is fixedly connected with a clamping seat 224, so that by utilizing the movable limiting function of the positioning rod 223 and the positioning sleeve 222, and the movable limiting function between the limiting block 214 and the positioning ring 221, when the limiting block 214 and the stopping strip 218 have more stability and guidance during the movement, meanwhile, the size of the semi-curved bar 216 and the size of the finger ring 217 are such that the movement stroke of the finger ring 217 is limited, thereby avoiding the situation that the stop bar 218 is separated from the stop hole 219, further increasing the stabilizing effect of the stop bar 218 and the auxiliary stop block 220 in cooperation.

Further, all seted up anti-skidding groove 225 on two half curved strips 216, the frosting line has all been seted up on the inner wall of two anti-skidding grooves 225, all movable mounting has friction cover 227 in two anti-skidding grooves 225, and the frosting line has been seted up on the surface of friction cover 227, the one side of two friction covers 227 all swing joint has gangbar 226, and the one side of gangbar 226 is connected on finger ring 217, utilize the frictional resistance between friction cover 227 and the anti-skidding groove 225 like this, make and hinder position strip 218 not in the middle of two assistance blocks 220, finger ring 217 can remove along with half curved strips 216 together, and then make the result of use of this device self better.

Further, the magnet plate 228 is embedded in the stopper bar 218, and the iron piece 229 is embedded in one end of each of the two auxiliary stoppers 220, so that the stopper bar 218 is less likely to be separated from the two auxiliary stoppers 220 by the attraction between the magnet plate 228 and the iron piece 229.

Further, the measuring mechanism 3 includes a mounting groove 310, the first body 110 is provided with the mounting groove 310, the inner wall of the mounting groove 310 is fixedly provided with a mounting seat 311, one side of the mounting seat 311 is fixedly provided with a measuring arc plate 312, the measuring arc plate 312 is uniformly provided with scale lines 313, the second body 114 is provided with fixing holes 315, and the outer diameter of the measuring arc plate 312 is matched with the inner diameter of the fixing holes 315, so that the medical staff can accurately obtain the separation angle when separating the first body 110 from the second body 114 by using the pointing head 314 and the scale lines 313 indicated by different positions, thereby comparing with the previous bone clamping angle, facilitating the medical staff to calculate whether the current bone clamping position is accurate more quickly, reducing the judgment difficulty of the medical staff, and improving the precision and reducing the difficulty of the medical staff in the operation process, let this device have humanized design more, also let the function of this device when using more comprehensive simultaneously, promote its applicable operation scope.

Further, a direction head 314 is fixedly installed on the second caliper body 114 on one side of the fixing hole 315, and a fixing block 316 is fixedly installed on the measuring arc plate 312 outside the fixing hole 315, so that the fixing block 316 is used for limiting the separation angle between the second caliper body 114 and the first caliper body 110, the usable range of the limiting arc plate 210 is avoided being exceeded, and meanwhile, medical staff is prevented from being injured by excessively opening the first clamping head 113 and the second clamping head 116 when releasing clamping.

The working principle is as follows: when the medical staff uses the forceps, firstly, the medical staff inserts fingers into the finger sleeve 111 and the finger ring 217, and then pulls the finger sleeve 111 and the finger ring 217 with the fingers, at this time, if the position blocking strip 218 is located between the two auxiliary blocking blocks 220, the extension spring 215 cannot pull up the moving plate 213 and the limiting block 214, so that the limiting groove 211 and the limiting block 214 generate limiting, namely, the first forceps body 110 and the second forceps body 114 are limited, but along with the outward force of the medical staff fingers and the fixation of the second forceps body 114 and the half-curved strip 216, the finger ring 217 can move along with the medical staff fingers, so that the position blocking strip 218 is pulled out, the adsorption limiting between the magnet plate 228 and the iron sheet 229 is released, and meanwhile, when the position blocking strip 218 no longer blocks the two auxiliary blocking blocks 220, the extension spring 215 releases elastic potential energy to pull up the moving plate 213 and the limiting block 214, namely, the limiting between the first forceps body 110 and the second forceps body 114 is released, the second body 114 and the first body 110 become movable, and the frictional resistance between the friction sleeve 227 and the anti-slip groove 225 makes the movable second body 114 and the finger ring 217 become a whole, so that the two are displaced together.

When medical personnel make this device carry out the centre gripping to the patient bone, medical personnel finger power makes first body of the pincers 110 and second body of the pincers 114 be close to each other, finally make first clamping head 113 and second clamping head 116 centre gripping the bone, the bone also makes spacingly to the motion of being close to each other of first body of the pincers 110 and second body of the pincers 114 simultaneously, this moment along with medical personnel finger inwards continue to exert oneself, can make the friction sleeve 227 remove in anti-skidding groove 225, even make hand ring 217 remove for second body of the pincers 114, and then drive and hinder position strip 218 and come in and go out again in two assistance blocks 220, make extension spring 215 stretched again and motion plate 213 insert spacing in spacing groove 211 again.

In addition, during the clamping process, the medical staff can observe the position of the scale line 313 pointed by the pointing head 314 to judge whether the clamping position is accurate.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
